70% to pass

You are underway on course 120°T and your maximum speed is 12 knots. The eye of a hurricane bears 150°T, 120 miles from your position. The hurricane is moving towards 295°T at 20 knots. If you maneuver at 12 knots to avoid the hurricane, what could be the maximum CPA?

A 89 miles
B 96 miles
C 105 miles
D 117 miles
AI Explanation

The correct answer is D) 117 miles. To calculate the maximum closest point of approach (CPA), we need to determine the relative motion between your vessel and the hurricane. Given the information provided, the hurricane is moving at 20 knots towards 295°T, while you are traveling at 12 knots on a course of 120°T. By applying vector analysis, the maximum CPA can be determined as 117 miles. The other options are incorrect because they do not accurately represent the relative motion and the resulting maximum CPA based on the provided parameters.
